DISPENSING-CAN.

Specification of Letters Patent.

Patented J une 21, 1921.

Application nled March 25, 1920. Serial No. 368,489.

T 0 all whom. t may concern Be it known that l. FRANK J. LAGINA, acitizen of the United States, and a resident of Clarkson, in the countyol Colfax and State of Nebraska, have invented certain new and use'lulImprovements in Dispensing-Cans, of which the following is aspeciiication.

My invention relates to improvements in dispensing cans.

An important object of my invention is to provide a can which may beheld in any position convenient to the user and yet will .dispense itscontents without difficulty.

A further object oi" the invention is to provide means whereby theliquid will be prevented trom flowing from the can when it isunintentionally inverted.

1 still further object is to provide means whereby the oil may be drawnfrom the can until it is practically empty, thus avoiding the necessityof too frequently having to lill the can.

Further objects of the invention will appear in the following detaileddescription, taken in connection with the following drawing1 forming apart of this specification, and in which l Figure 1 is a vertical crosssecticnalview of the apparatus,

Fig. 2 is a plan view ot the same, and,

Fig. 3 is an enlarged view of one of the valves upon the ends ot thesupply pipe of the apparatus.

ln the accompanying drawing, wherein similar numerals refer to similarparts throughout the same, the numeral 4 indicates the body portion ofmy dispensing' can upon which is iitted a top 5, having an aperture 6fitted with a screw cap, whereby the can may be filled. An aperture 7 isformed in the center of the top 5 and a cylinder 8 is fitted therein. lnthe top 9 upon the cylinder 8 is formed a. nozzle'portion 10 throughwhich the liquid maybe dispensed.

A piston 11 in the cylinder 8 is formed of a metallic disk 12 to theupper surface of which is attached a disk 13 of leather or any materialwhich will make an air-tight connection with the walls ol' the cylinder.A spring strip 14 is attached to the upper tace oit the piston 11 bymeans oic screws or rivets through to the metallic disk 12. A disk checkvalve 15 at the tree end oic the strip 14 is adapted to be seated uponan aperture 16 in the piston. The piston l1 is rgidlv attached to theend ot one 17 ot ua U- shaped rod 18 which passes up into the cylinder 8from the body portion 4 through'an aperture 19 in the bottom 2O of thecylinder. Suitable packing units at the aperture insure a tight jointbetween the bottom of the cyllnder and rod 18.

To the lower portion ot the other arm 21 of the member 18 is rigidlyattached a ring 22 which is connected to a coil spring; mounted on thearm 21ot the rod 18. kThe arm 2l passes up through an aperture 24 in thetop 5 of the can and has a lever 25 pivotally attached to its upper end.Thelever is pivotally connected to the upper portion of a link 26 whichis itseltlpivotally connected to the top o" the handle 2'? of the can.The lever 25 is bent downward and its lower portion 28 serves as a pumphandle fulcrumed upon handle 27 whereby the piston 11 may be caused toreciprocate within vthe cylinder 8.

Vlithin the body portion 4 of the can is a pipe 29 extending from apoint near the bottom to a point near the top of the can. A rightanffled pipe 30 has one of its arms connected to pipe 29 about midway ofits length while its other arm is fitted within an aperture 31 inthebottom 29 of cylinder 8. A disk check valve 32 upon a springr strip 33riveted to the bottom of cylinder 8, as shown, is adapted to be seatedupon the aperture 3l. @ne end of a metallic or suitable strip 34 issecured to the ipe 29 midway of its length, as shown. lever 35 ispivotally secured to the free end of the strip 34.

A. weight 36 is mounted upon one end of lever 35 while two links 37 and38 are pivotally connected to the opposite end of lever 35. Link 37 ispivotally connected at its farther end to a valve arm 39 fulcrumed upona bracket 40 attached to the pipe 29 near its upper end.

A disk valve 41 is mounted at the tree end of valve arm 39 and isadapted to be seated upon the upper end of pipe 29. The lower end ot thepipe 29 is closed by a valve 42 on a valve arm 43 fulcrumed upon abracket 44 on the lower end of pipe 29 and pivotally connected to thelower end of link 38.

It will be seen that when the can is inverted, weight 36 upon level` 35will drop and so will always alternately open and close valves 4:1 and12, with the lowermost valve always open. yllhe purpose of the pipes 29and 39 is to keep the weight of the liquid in the can from opening checkvalves 32 and 15 and flowing from the can should the can'be accidentallyinverted. Since the lowermost of the two valves l1 and 42 is always theopen one, the liquid may be pumped from the can until it is almostempty. l

Considering the top of the can to be uppermost, when valve 42 at thelower end of pipe 29 will be open, the operation of my apparatus is asfollows; rlhe can is first filled with oil or any desired liquid througithe opening 6 and the cap is then screwed upon the opening. By applyingsufficient pressure to pump handle 28 the U-shaped rod will be forcedupward against the action of spring 23 and will cause the piston 11 incylinder 8 to move upwardly. When handle 28 is released the spring 23will pull rod 18 and piston 1 1 downward again. rlhe upward movement ofpiston 11 will tend to form a vacuum below the piston and this will opencheck valve 32 and draw oil Vup from the body of the can through thelowermost end of pipe 29 and into cylinder 8. 0n the next downwardmovement of piston 11 the oil below the piston will open check valve v15and will pass up through aperture 16 and so will be above the piston.The next upward movement of the piston willdraw more oil into cylinder 8through check valve 32. 1t will be seen that after continuing thereciprocating movement of piston 11 for a few strokes sufficient oilwill be above piston 11 to-pass out of nozzle 10.

rllhis same mode of operation will apply no matter what position the canis in, except that when the can is heldin any position which will causeweight 36 to swingtowarr valve 41 on pipe 29 that valve will open andoil will be drawn into cylinder 8 through that end of pipe 29.

1t is to be understood that the form of my invention shown and describedis to be taken as a preferred example of the same and changes in thesize, shape and arrangement of parts may be' resorted to withoutdeparting from the spirit of the invention or the scope of theVsubjoined claims.
